Specification of Letters Patent.

Application filed February 12, 1910. Serial No. 543,614.

To all whom t may concern:

Be it known that Janine T. A\Nniinw, a citizen of the United States,residing at Mont goinery,in the county of Montgomery and State ofAlabama, have invented certain new and useful Improvements in`Safety-Wheels for RailwayeCars; and I do hereby declare the followingto be a full, clear,.and exact description of the invention. such aswill enable others. skilled in the art vto which it appertaiiis to 'makeand use the same.

My invention i'elaltes to improvement in the lmanufacture of wheelsintended for use in connection with my safety appliance for forth, forexample, in .Patent No. 941,222, dated November '23, 1909.

The object of 'my invention iste manutan:- ture, .in a. simple andeconomical ways a car or locomotive wheel having outside and insidetreads in addition. to the main central tread,-and also to provide.means where-by an additional wheel or Wheels having safety treads maybe applied to the ordinary car or locomotive wheel Withontfrenioving itfrom the truck. lilith these objects in View, my invention consists inthe construction and combinations of parts as hereinafter described andclaimed.

In the accompanying' drawings-Figure 1 is a side elevation of onecornerof a truck, showing my invention applied' to the Wheel thereof.Fig. 2 is a vertical. cross-section through my improved wheel.' Fig. 3is a side View ofv one of the auxiliary Wheels. Fig. 4 is a side view ofthe inside Wheel applied to the main wheel, lookingfrom the inside ofthe truck. Fig. 5 is a rear View, partly in section,of a truck, showingmy iniproved wheel. applied to the Wheels thereof. Fig. 6 is an enlargedsectional view of the car wheel shown in Fig. 5, and Fig. 7 istJsectional vievv of the auxiliary Wheel applied to the Wheels of the ponytruck of a locomotive.

1 represents a car or locomotive wheel made in the usual manner, exceptthatit is provided at intervals with iprojecting lugs or bosses 9.,which are per orated for the which is applied to the main Wheel 1, isannular in shape, is provided with an outside tread 5, with an inclinedprojecting portion 6, and with an internal ring or projection 7, fittingwithin the edge of the main car wheel, slightly wheel l.

pcrforations S for the passage of the bolts 3, and on its inner face isprovided with a f series of lugs 9, two of said lugs being arranged inproximity' to each hole 8, as shown in Fig. 3. The inner wheel 10 isprovided with a fiange 11 and a part 12, fitting against the inside partof the main wheel 1. The wheel 10 is made in two halves, as shown inFig. 4f, and is annular in shape. By this construction, the inner Wheelmay be fitted directly` to a car truck of the usual pattern Withoutremoving the wheels from the truck, and the outer Wheel may be fitteddirectly against the wheels o truck Without removing said wheels fromsaid truck. In fitting these auxiliary wheels to cars and locomotives ofordinary ,construction, 'the lugs or bosses be absent, but stillthereonstruction would be eicient for the purposes desired. One idea ofthis invention, however, is to .have these lugs or bosses 2 made.integral with the wheel l during the process of making, so that at anytime the auxiliary inside or outside wheels may be attached thereto. Onthe inner part of the two-part wheel l0, a circular depression isformed, and in this depression is located a ring 13, preferably ofmetal, through which the bolts 3 pass, said bolts being provided withsecuring nuts 14: ateach end. The ring 13 is made in two parts, as shownin Fig. et, but the joints iii the ring are arranged at diil'erentpoints from the joints in the Wheel 10.

In Fig. 2 is shown a wheel having auxiliary wheels on both sides, makinga coinpound Wheel. In Figs. 5 and 6, an auxiliary car wheel is shown,which maybe attached to the inside of the car Wheel with out removingthe saine from the truck, by reason of the 'twopart construction alreadydescribed, and in Fig. 7 is shownA-an auxiliary wheel adapted to beapplied to the outside of a wheel on the locomotive pony truck, saidpony truck being so constructed that an auxiliary wheel may be appliedto the outside thereof without interfering with the journals orbearings. In Fig. 5, the inside Wheel 10'acts as a safety wheel incaseof derailment, as described in my patent above referred. to, and on theoutside thereof are mounted safety rollers 15, as also dethe locomotivepony 2 4would/of course,

the outside wheel being ofy scribed in said patent. By referring toFigs. 6 and 7, it will be obvious that the auxiliary wheel may beapplied to the inside of a car wheel or the outside of a locomotive ponytruck wheel, Without removing the wheels from the trucks.

In case the wheels are manufactured for the first time as a whole, asshown in Fig. 2, it is not necessary to have the inner wheel made in twoparts, this construction being adopted for convenience in applying theauxiliary wheels to the car wheels now in use.

1. The combination of a car or locoinotive wheel, providedwitli'perforated bosses, and an auxiliary wheel adapted to vbe fittedagainst. said rstnamed wheel and having parts engaging saidbosses, saidauxiliary wheel being provided with arts conforming in shape to the shae of t e main wheel, so that they may be clbsely fitted together, andmeans for securin said wheels together, substantially as descri ed.

'2. T lie combination of a ear or locoinotive Wheel, provided withperforated bosses, an annular auxiliary wheel provided with parts soshaped that it may fit closely against thc main w eel, said auxiliaryWheel being provided with lugs extending on either side of saidperforated bosses, and bolts and nuts passing through said bosses andbinding both of said wheels together,.substantially a described.

3. A safety wheel adapted to run on a prepared track, composed of a maincentral wheel havinga flange and two auxiliary wheels adapted to fitclosely against the inain wheel and to be secured there-to, each of saidauxiliary wheels being provided with a flange, subst-ant-iallyasdescribed.

4. A safety wheel composed of a central wlieel provided with a guidingflange and auxiliary wheels adapted to b"e secured to and rest closelyagainst the faces of said wheel, and means for securing the three wheelstogether, the inner wheel being made and auxiliary wheels adapted to besecured against said central wheel, the outer auxiliary wheel bein@rprovided with lugs located on either si e of said bosses, and the innerauxiliary wheel being made in tWo parts` each of said auxiliar wheelsbeing provided with a flange, an bolts passing through all three of saidwheels and uniting them together, substantially as described.

7. A safety wheel composed of a central main wheel having a Harige andperforated bosses, and two auxiliary wheels adapted 4to be fitted oneagainst each :face of said main wheel, and having portions closelfitting against the sides of said main w eel, the outer wheel being madein one piece and having a pair of lugs embracing each of the outwardlypro]eeting on the main wheel, and tlie.inner wheel being annular andmade in two halves, and a two-part ring located in a recess in saidsecond named wheel, both of said auxiliary Wheels being provided withanges and bolts passing through said wheels, bosses, and rings andprovided with securing nuts, substantially as described.

f In testimony whereof, I affix my signature, in presence of twowitnesses.
